Scavenger receptor class B type I regulates cellular cholesterol metabolism and cell signaling associated with breast cancer development.

Abstract

Previous studies have identified cholesterol as an important regulator of breast cancer development. High-density lipoprotein (HDL) and its cellular receptor, the scavenger receptor class B type I (SR-BI) have both been implicated in the regulation of cellular cholesterol homeostasis, but their functions in cancer remain to be established.
